Details:

In today's guile 1.9 (and since a while ago), line number and column reported
by the repl on entering the debugger are wrong (they seem to always point some
lines above the actual error).

E.g., loading this file:

    (define-module (foo))

    (define k 3)

    a

reports the undefined `a' error as:

    scheme@(guile-user)> (load "foo.scm")
    ;;; compiling foo.scm
    ;;; compiled /home/jao/.cache/guile/ccache/2.0-0.RLE-4/home 
/jao/tmp/foo.scm.go
    foo.scm:1:1: In procedure module-lookup:
    foo.scm:1:1: Unbound variable: define-modue
    Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
    scheme@(guile-user) [1]> 

i.e., line 1 instead of line 5.

Follow-up Comment #1, bug #30903 (project guile):

Sorry, pasted the wrong error trace. Here's the real one:

;;; compiling foo.scm
;;; compiled
/home/jao/.cache/guile/ccache/2.0-0.R-LE-4/home/jao/tmp/foo.scm.go
foo.scm:3:1: In procedure module-lookup:
foo.scm:3:1: Unbound variable: a


i.e., line 3 instead of line 5.

Follow-up Comment #2, bug #30903 (project guile):

Indeed.  See
http://www.gnu.org/software/guile/docs/master/guile.html/Source-Properties.html#Source-Properties
for the reason: `a' does not have any source properties associated with it.

To fix this, we would need a reader that returns an annotated datum instead
of trusting to the source-propreties whash.
